Suppose an average person blinks 15 times per hour. How many times does an average person blink in a year? Write the answer in scientific notation (Hint: 1 year = 365 days, 1 day = 24 hours).(1 point)
To calculate the number of blinks in a year, we need to multiply the blinking rate per hour by the number of hours in a day and the number of days in a year.
Number of blinks per year = 15 blinks/hour x 24 hours/day x 365 days/year
Number of blinks per year = 131,400 blinks/year
In scientific notation, this is written as 1.314 x 10^5.
